Possible degradation of driving performance exhibited by participants of driving simulation experiments. Participants were expected to exhibit an increase in performance as they learned to interact with a driving simulator. And then after some amount of driving, performance was expected to decrease as participants became bored or tired. A review of previous driving simulation studies suggested that there is a general rule-of-thumb to limit the driving time or the time to participate in a driving simulation study to one hour. A driving simulation study was designed to examine whether driving performance would degrade within an hour of driving. The experiment was designed with the roadway geometry and time driving as independent factors and the lateral position and travel time as dependent factors. One driving scenario was developed with 122 simple horizontal curves alternating with 122 straight road sections. The simulated driving condition was a level, two-lane rural road, with a posted speed limit of 55 mph, without any traffic. Twenty participants drove the scenario in either a RS-100 or RS-600 driving simulator. Eight participants completed the entire scenario. Of the twelve participants who chose to stop the simulation before finishing the scenario, six did so after 55 to 65 minutes of driving, and four drove even longer. This result suggests that the rule-of-thumb may actually be a practical limit, representing the amount of time a participant is willing to drive. The performance on each curve and straight segment was translated into a cost, defined as the product of the absolute value of the standard deviation and the travel time. The cost on the curves was analyzed separately from the cost on the segments. The data for 60 curves and 60 segments near the end of the scenario were fit to a linear trend line to examine whether performance degraded over the latter half of the drive. Some participants exhibited performance degradation on both curves and segments, some only on curves, some only on segments, and some exhibited performance improvement on both curves and segments. The performance trends observed for this experiment did not support the one hour driving time limit rule-of-thumb.
